Habitat Stability to Climate Change

  • Use various climate variables

– What is available – What do you believe is important

  • Can use a variety of proxys for habitat

– Land Cover – Vegetation – Biome

  • This study was done in a data rich area
  • Use proxys where possible
  • Don’t limit one’s self to the categories used

– Water may not be the most important ecosystem service

  • If you can show one variable is more important than another,

weight it accordingly

  • There are other tools to model habitat change/stability
